Also the Linux kernel is definitely not a one-man project, although it has a
chief architect (Linus Torvalds). It consists of lots of separated
subsystems (kernel core, networking, file systems, isdn, drivers, scsi,
console code, tty subsystem, ...) and has also separated architecture
specific code sections. All these have their own maintainers or groups of
maintainers with only minor overlap. The largest part of Linux are the
drivers which have all their own maintainer.
Then there are of course lots of other important parts of the systems
which are developed by other people, like XFree86 or the C Library.
To get back on the topic. Simple OS without advanced features like
networking or virtual memory are not that difficult to build. For an
example see UCOS. Another smaller OS available in source is vsta (it has
virtual memory and networking, but it still much simpler than Linux)
These are writen in C, but they probably could be writen in Ada as well.
